Numbers can lie -- yet they're the best first step in determining whether a stock is a buy. In this series, we use some carefully chosen metrics to size up a stock's true value based on the following clues:
- The current price multiples.
- The consistency of past earnings and cash flow.
- How much growth we can expect.
Let's see what those numbers can tell us about how expensive or cheap Apple
The current price multiples
First, we'll look at most investors' favorite metric: the P/E ratio. It divides the company's share price by its earnings per share (EPS) -- the lower, the better.
Then we'll take things up a notch with a more advanced metric: enterprise value to unlevered free cash flow, which divides the company's enterprise value (basically, its market cap plus its debt, minus its cash) by its unlevered free cash flow (its free cash flow, adding back the interest payments on its debt). As with the P/E, the lower this number is, the better.
Analysts argue about which is more important -- earnings or cash flow. Who cares? A good buy ideally has low multiples on both.
Apple has a P/E ratio of 15.1 and an EV/FCF ratio of 11.0 over the trailing 12 months. If we stretch and compare current valuations with the five-year averages for earnings and free cash flow, we see that Apple has a P/E ratio of 33.9 and a five-year EV/FCF ratio of 25.4.
A positive one-year ratio of less than 10 for both metrics is ideal (at least in my opinion). For a five-year metric, less than 20 is ideal.
Apple is 0-for-4 on hitting the ideal targets, but let's see how it stacks up against some of its competitors and industry mates.

Numerically, we've seen how Apple's valuation rates on both an absolute and relative basis. Next, let's examine ...
The consistency of past earnings and cash flow
An ideal company will be consistently strong in its earnings and cash-flow generation.
In the past five years, Apple's net income margin has ranged from 14.2% to 23.9%. In that same time frame, unlevered free cash flow margin has ranged from 19.3% to 30.7%.
How do those figures compare with those of the company's peers? See for yourself:

In addition, over the past five years, Apple has tallied up five years of positive earnings and five years of positive free cash flow.
Next, let's figure out ...
How much growth we can expect
Analysts tend to comically overstate their five-year growth estimates. If you accept them at face value, you will overpay for stocks. But even though you should definitely take the analysts' prognostications with a grain of salt, they can still provide a useful starting point when compared with similar numbers from a company's closest rivals.
Let's start by seeing what this company's done over the past five years. In that time period, Apple has put up past EPS growth rates of 64.9%. Meanwhile, Wall Street's analysts expect future growth rates of 19.6%.
Here's how Apple compares with its peers for trailing-five-year growth:

The bottom line
The pile of numbers we've plowed through has shown us the price multiples that shares of Apple are trading at, the volatility of its operational performance, and what kind of growth profile it has -- both on an absolute and a relative basis.
The more consistent a company's performance has been and the more growth we can expect, the more we should be willing to pay. We've gone well beyond looking at a 15.1 P/E ratio, and we see that Apple's EV/FCF is just 11.0. If we include its marketable securities in its cash balance (as most people do), that number slips below 10.0. On a five-year basis, these numbers are much higher, but that's due to Apple's tremendous growth.
We see that Apple's margins aren't quite up to Microsoft's or Google's, but Apple makes hardware while the other two are software-driven. Given that, Apple's margins are quite strong.
The reason Apple is trading for such low multiples is that the market is doubting its ability to grow given how big it is and noting both the burgeoning competition and the loss of Steve Jobs. As an Apple shareholder, I'm happy holding my shares at this point. But all this is just a start. If you find Apple's numbers or story compelling, don't stop here.
